K. 333 (315c), 284 (205b), 454, in this order. FIRST EDITION. Dedication: "Dediées A Son Exellence Madame La Comtesse Terese De Kobenzl Née Comtésse de Montelabate, Epouse de son Exell. Monsieur Le Comte Louis de Kobenzl Ministre Plenipotentaire de S. M. J. R. Ap:&:&. à la Cour de Sa Maj: Imperatrise de toutes les Russies &.&. par son très humble et très Obeisant serviteur Christoph Torricella Marschand d'Estampes et Editeur de Musique &.&." 53 pages (violin part for K. 454 missing). Richly decorated engraved title page (with two coats of arms, pictured in Haberkamp, II, 93). No VN. Ref.: Haberkamp, 138/40; Hirsch IV, 18; RISM M 6798. Viennese publishers, like Artaria and Torricella, vied with each other for the most beautifully engraved frontispieces. The elaborate dedication here to The Countess of Cobenzl is not by "Monsieur" Mozart but by the publisher. Mozart writes to his father on 12 June 1784, "I have given three others [sonatas] to Torricella, the last of which is the one in D, which I composed for [Baron Thaddäus von] Dürnitz in Munich." He is referring to K. 284 (205b) now known as the "Dürnitz Sonata." Regarding the first version [discarded] of the Allegro movement of this sonata, see László Somfai, "Mozart's first thoughts: the two versions of the Sonata in D major, K. 284," Early Music 19 (1991), 601-13. Includes three typewritten notes containing information on this edition.

K. 608. FIRST EDITION. Engraved title and music. VN 75. 1f.20xr. Ref.: Haberkamp, 346/47; RISM M 7177; Köchel, 6th ed., 694. This work was originally composed as "Ein Orgelstück für eine Uhr" and so entered by Mozart in his own Verzeichnüss on 3 March 1791. However, in the above form it received its first publication. According to Constanze Mozart, in her letter to Johann Anton André, dated 26 November 1800 (Bauer-Deutsch IV #1322, lines 91-94), the four-hand piano arrangement was made by Johann Mederitsch, named Gallus.

Loeb Music Library's copy likely the 1st ed. of the piano solo version (K. 359). Mozart probably wrote this set of variations for one of his aristocratic piano pupils, Countess Maria Karoline Theinnes de Rumbeke. The theme is an anonymous French chanson.
